А dark-violet knight with a most gloomy and never-smiling face. He rested his chin on his chest, he did not look at the moon, he was not interested in the earth, he was thinking something of his own, flying beside Woland.

"Why has he changed so?' Margarita quietly asked Woland to the whistling of the wind.

This knight once made an unfortunate joke,' replied Woland, turning his face with its quietly burning eye to Margarita. 'The pun he thought up, in a discussion about light and darkness, was not altogether good. And after that the knight had to go on joking a bit more and longer than he supposed. But this is one of the nights when accounts are settled. The knight has paid up and closed his account.'
